Subject: musl: Add aliases for glibc provided libraries
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=3b993fc618684896e492a7d3bdcaef65ec5aab54;p=thirdparty%2Fopenembedded%2Fopenembedded-core-contrib.git

musl: Add aliases for glibc provided libraries

This is a step towards running pebuilt applications for glibc  on musl
There are many realworld applications which are not always built from
source, especially provided by third party

Package the glibc symlinks into new package musl-glibc-compat
